Abstract
Official abstract text for this publication.
A flux containing: a rosin; a solvent (S); a thixotropic agent; and an activator is disclosed. The rosin contains a rosin amine. The solvent (S) contains a first solvent (S1) having a boiling point of 250° C. or less, and the amount of the first solvent (S1) relative to the total amount of the solvent (S) is 50% by mass or more and 100% by mass or less.
First claim
Opening claim text (preview).
What is claimed is: 1 . A flux comprising: a rosin; a solvent (S); a thixotropic agent; and an activator, wherein the rosin comprises a rosin amine, the solvent (S) comprises a first solvent (S1) having a boiling point of 250° C. or less, and an amount of the first solvent (S1) relative to a total mass of the solvent (S) is 50% by mass or more and 100% by mass or less. 2 . The flux according to claim 1 , where the boiling point of the first solvent (S1) is 150° C. or more and 250° C. or less. 3 . The flux according to claim 1 , wherein the solvent (S) further comprises a second solvent (S2) having a boiling point exceeding 250° C. 4 . The flux according to claim 1 , wherein the rosin amine comprises dehydroabietylamine. 5 . The flux according to claim 4 , wherein the rosin amine further comprises dihydroabietylamine. 6 . A solder paste comprising: a solder alloy powder; and a flux of claim 1 .
